Dell PowerFlex is a high-performance, software-defined infrastructure platform designed for mission-critical workloads. It combines compute and software-defined storage in a flexible, scalable arch.

Independent Scaling of Compute and Storage PowerFlex allows us to scale compute and storage resources independently. This disaggregated architecture is extremely valuable for optimizing costs and right-sizing infrastructure based on workload demands particularly in environments with variable AI and database workloads. High Performance with Low Latency With support for NVMe, RDMA and a fully distributed architecture, PowerFlex delivers consistent low-latency performance. This is critical for applications like AI model training, real-time analytics and Tier-1 transactional databases. Flexible Deployment Options The ability to deploy PowerFlex in hyper-converged (HCI), two-layer or mixed architectures provides design flexibility for different customer needs. Whether they're building a private cloud, extending hybrid cloud capabilities or deploying in a DR configuration. Automation via PowerFlex Manager PowerFlex Manager simplifies complex operations such as provisioning, lifecycle management and policy enforcement. This helps reduce operational overhead and improves IT agility. Resiliency and Self-Healing Architecture The platform offers zero-impact rebuilds and built-in fault tolerance across nodes and disks, making it extremely reliable for business-critical workloads. Integration with AI and Kubernetes Ecosystems With support for CSI drivers and GPU-enabled infrastructure, PowerFlex fits seamlessly into modern DevOps and AI/ML pipelines allowing us to serve next-gen workloads without needing separate infrastructure stacks.

Performs well, effective, and has responsive remote technical support

Sunlight is a scalable solution. It supports on-premises and distributed deployments, as well as public deployments. It has a single pane of management so I can manage all of my VM installations in a distributed manner. It also has a footprint, that allows me to operate on Edge. If for example, you have a retail shop with 2,000 locations and they use a networked point of sale system, or if you are Chipotle and they have so many locations and they have to use a backend system at each location. At the moment, these are all standalone systems that operate with very little connection to the central. We could, however, connect and create a network using Sunlight. We can virtualize and run with Edge thanks to Sunlight. This allows us to operate and obtain high-end computing on Edge for retail. Sunlight is a startup. I am not sure how many users they have, but we have been using it constantly and using the technology to bring in customers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The API catalog helps us use Ansible automation."

"Dell PowerFlex is a highly scalable solution."

"The resiliency and data protection are the most valuable features."

"We are planning to upgrade this system in three years, but in the meantime, we are happy with VxFlex."

"The solution was connected to alternate storage, and it provides great scalability and reliability."

"The technical support for this solution is pretty good."

"The integration with AWS is a valuable feature."

"PowerFlex allows us to scale compute and storage resources independently, which is extremely valuable for optimizing costs and right-sizing infrastructure based on workload demands, particularly in environments with variable AI and database workloads."

More Dell PowerFlex pros

"It supports the latest technology of NVMe SSD, which is PCIe-based SSD. It has a very good IOPS performance as compared to vSAN. For the same system, I get 1,000 IOPS with vSAN, and with Sunlight, I am able to get almost 10,000 IOPS. In terms of features, it has almost all the features, such as HA and centralized dashboards. It can be managed centrally, and the visibility of the system is very good. They also have very good technical support and customer or partner training."

"If I had to use VMware or Nutanix, the same application would take three nodes and provide 400,000 IOPS, or input-output operations, but with Sunlight, I can get four million IOPS for the same price, allowing me to run an application on much less hardware."

"The performance and small footprint of this solution are its most valuable features. I am able to obtain and use more than 90 percent of the physical hardware capacity."

Cons

"The initial deployment was complicated and required a lot of data nodes, IPs, internal vLANs, data vLANs, and many other things."

"I think that stability is good for small and mid-level environments, but I don't think that it is suitable for high-end."

"The solution’s automation and pricing could be improved."

"I would like to see a more user-friendly interface."

"The support of containers needs to be improved. At present, it is limited to VMware. There needs to be direct communication with the hardware rather than through a hypervisor."

"I am not really impressed by the technical support of this solution. The product really needs better and more support."

"The solution must be more flexible."

"We've had some issues around the licensing. There were some issues in terms of using the VMware license."

More Dell PowerFlex cons

"My recommendation would be to add this technology to Azure, Microsoft Azure so that we can bring it to the market, or deploy it on public clouds such as Microsoft Azure and Google. It is currently only available on Amazon's public cloud."

"Its reporting and dashboards need to be improved. It currently has very basic reporting options. It should also be made easier to deploy on Unix operating systems. It is easy to deploy on Windows and Linux, but it is currently not easy to deploy on Unix."

"It lacks the bells and whistles that are typically associated with Amazon Services or Nutanix."

Pricing and Cost Advice

"From my perspective, pricing is expensive. If they can reduce the pricing or offer more customer incentives, it would attract more users."

"The solution's price is medium."

"I rate the solution's pricing an eight out of ten."

"The solution's pricing could be much cheaper and affordable."

"The product is expensive."

"The solution is expensive and I give the cost a two out of ten."

"We have a good contact in Dell and he prepared all the information and provided everything to us."

"The price of the solution is fair, it is priced in the average range amongst competitors."

More Dell PowerFlex pricing and cost advice

"There is an operating cost for the VDIs, which is an additional cost. However, the licensing fee is half that of VMware or Nutanix."
